[PATCH RFC next 17/18] scripts/Makefile.build: do not run kernel-docs with warnings

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

We have too many of them for now and the kernel has switched to a Python
script with likely many other small changes. We also have a couple of
patches in our fork, so it'll need to be ported to the new version once
sync'ed.

For now, let's simply not run kernel-docs with warnings, which allows us
to use W=e to enable Werror for host and target compilers as well as the
linker and assembler. This will then be used in buildman in next commit.
